Abstract

We report the clinicopathologic features of two cases of respiratory epithelial adenomatoid harmartoma (REAH) of the sinonasal tract. Hamartomas are rare in the nasal cavity. Histologically, these lesions were characterized by a glandular proliferation lined by ciliated respiratory epithelium originated from the surface epithelium. The two patients were evaluated by a gastroenterologist to assess intestine colocalization. The treatment was a complete surgical resection through limited approach. We should be aware of this entity as a differential diagnosis for inverted papilloma and well-differenciated adenocarcinoma. Fine histopathological analysis is necessary to avoid aggressive surgery for this benign lesion.
